What kind of TV did Admiral make in 1948?
Admiral produced seven TVs with Bakelite console cabinets. In 1948 and 1949, models 20X122 and 24A12 had round 10-inch picture tubes. These 10-inch sets are easily distinguished by the diagonal pattern of their speaker grilles. The other Bakelite consoles have a rectangular grille pattern and larger picture tubes.
What kind of TV is the Admiral 24a12?
Model 24A12 is one of many popular Admirals from the 1940s and 1950s. Its 20A1 chassis is nearly identical to the 20B1 chassis in the Model 24C15 that I restored last year. The difference is that this TV uses a 10-inch picture tube and the other has a 12-inch tube. Here are photos of the 24A12 and 24C15 after restoration.
Why are there lines on my Admiral TV?
You can eliminate these retrace lines by adding two little parts: a resistor and capacitor. The lines appear because the TV lacks a circuit to blank the video scanning beam during the TV’s vertical retrace interval, when the position of the beam is returned from one side of the screen to the other.
